CONTAINER.

This invention relates to foldingboxes usually manufactured of cardboard, although the invention may be applied to containers of paper or other material.

The object of the present invention is to provide an improved form lof folding box structure which can be manufactured from a single blank and easily and quickly folded into box form, the boxwhen folded beinga complete container and'providedwith interlocking features so that it cannot open or spread. In theparticular form of the invention illustrated and ldescribe-d, a box is shown suitable for the packaging of pneus matic tubes, but the principles ofthe invention may be applied to boxes'or containers of other shapes and of all sizes and proportions` and the invention is not limited to the exact detailsj' or arrangement of parts shown herein.;

Other objects and advantages are provided by the improved structure in which are secured simplicity, ease of folding, and complete interlocking of the various elements of the box in folded form.

In the drawings is shown the preferred form of the invention, in which p Figure 1 is a plan view Iof the box blank with the various lines of folding indicated thereon;

Figure 2 is a perspective view of the box at the /completion of the first folding operation,

Figure 3 is a longitudinal section on the line 3--3 of Figure 4 showing the third folding operation partially completed;

Figure 4 is a view looking into the box of Figure 3;

Figure 5 is an enlarged perspective of the open end of the box;

Figure 6 shows the box in folded form with one form of interlock;

Figure 7 is a section of Figure' 6 on the plane 7 7 ofthe latter figure;

Figure 8 is a view of the same boxl folded in slightly different form; and

Figure 9 is a section on the line 9--9 of Figure 8 v In describing the invention' the yform of blank shown in Figure l'will first be detailed, the terms, front, ends, side'back, etc.,

referring to the position of the various parts of folds of the blank as they are situated in the completely folded box of Figures 6 and 8.

The blank shown herein is the form substantially of a ractangle cut to shape and scored so as to facilitate folding, the scoring dividing the blank into the various parts as will be described. 1 is the bottom ofthe box, 2 the top, 3 the closed end land 4 the open end. These four elements of the finished box are arranged in a line through the center of the blank, the open end carrying a small. locking tab 5 which is also in line with the four parts just described. At the sides of the bottom 1 are the parallel side walls 6 and at the sides of the top 2 are similar parallel side walls 7 which, for the sake of distinguishing, may be termed the bottom and top side walls respectively.

At the sides of the closed end 3 are located the' gussets 8 which lie between the side walls 6 and 7 and are preferably scored by crossing diagonal scorings 9 4to facilitate the folding of the box. This scoring may be of any preferred form so that the gussets will fold properly. In the form illustrated, there is shown a species of scoring such as covered in my prior Patent No. 1,230,67 5 of June 19, 1917. The gussets are rectangular in shape, but do not extend quite to the edges of the side walls between which they are located, the outer edges of the gussets thereby not interfering with the folding of the box.

At' the ends of the top side walls arev formed wings 10, the outside edges of which are inset slightly, as at 11, so as-not to interfere with the tucking-in ofthe wings. The outside corners of the wings are scored upon diagonal lines to form small-triangular tips 12. The inside corner of each wing is cut away on a diagonal line 13, a small projection 14 beingleft at the inside corner to effect interlocking of the box.

At the ends of the bottom side walls and at either side of the open end are provided flaps 15 which are substantially rectangular, but the edges of which arev set in from the outer edges of the side walls and open end so as not to interfere with the folding Each flap is scored as at 16 in the same manner as the gussets so that it can fold together when the box is formed in shape and thereby form pockets adapted to receive the wings and tips when the box is folded or set up. In the top, slightly set back from its outer edge, is arranged a transverse slit 25, which provides a bri ge piece 26 and the edge may be cut out to form a notch 17. The tab 5 is formed I with oppositelyl arranged lpairs of cuts 18 /i-d 19, onv its edges the former cuts being vshort and close to the open end. The latter cuts are somewhat longer and are spaced from the open end a distance equal to the width of the bridge piece 26.

Having described fthe blank as it is cut out, lthefolding operations and the construction of the finished box will. be understood.

The first 'operation is Ato bring the side Walls at right angles to the blank to the.

of the space 23. As the open end 4 is brought up the wings 10 are located within' the pockets formed by the folds of the flap and the tips 1.2 are secured 4within t-he pockets formed by the folds so that the wings are securely locked in place. The projections 14 will interlock with the cuts 18 while the tab 5 passesbeneath the top. The

A notch 17 provides a purchase for opeing the box.

If.a further interlock for the open end is desired, the tab may be passed through the slit 25, in which case the cuts 19 will interlock with the slit. The bridge 26 may be pressed inwardly to release the'open end.'

The box formed in the manner stated is easy and inexpensive to manufacture and will securely hold when in folded condition. The invention. is not necessarily limited to the utilization of every feature in a single box, as some of them'may be utilized with out all of the other features. v

What is claimed is:

` i 1. A folded box made from a oneepiece blank comprising a sheet of materialhaving defined therein a top, closed end, bottom and open end in a line through the center of the sheet, top and bottom slde walls laterally of the top and bottom, respectively, flaps located in the angles between the bottom side A walls and the open end, each flap being subdivided by score lines into a plurality oftriangular areas which are adapted to form pocket-s when folded, wings proiecting beyond the ends of the top side walls, and tips upon said wings and defined therefrom by score lines, so that when the box is folded,

' the top.

are adapted to lie in overlying pockets,4

-whereby an interlocking closure mayv be formed when the box is set up.

2. A folded4 box made from a one-piece blank comprising a sheet of material having defined therein a top, closed end, bottom and open end in a line through the center of the sheet, top and bottom side Walls laterally of the top and bottom, respectively, flaps located in the angles lbetween the bottom side `\walls and the open end, each flap being subdivided by score lines into a plurality of triangular areas which are adapted to form a pocket when folded, and wings projecting beyond the' ends of the v'top side Walls, so that when the box is folded, the .wings are adaptedto lie within the pockets formed by lthe folds of the flaps, whereby an interlocking closure may be forined 'when the boXiS set up.

3. A folded box made from a one-piece blank comprising a sheet of material having defined therein a top, closed end, bottom and open end in a line through the center of the sheet, top and .bottom side walls laterally of' the top and bottom,- respectively, gussets between the-top and bottom side walls, said gussets being scored so as to fold together, flaps located in the angles between the bottom side walls and the open end, 'each flap being subdivided by score lines into a plurality to triangular areas which are adapted to form 'pockets when folded, wings projectying beyond the ends of the top side Walls,

tips upon said wings and defined therefrom by lscore lines, so that when the box is folded, the wings are adapted -to lie within pockets formed by the folds of the flap and the tips are vadapted to lie in --overlying pockets, whereby an interlocking closure may be formed when the box is set up, anda `tab ex-I tending beyond the open end adapted to form an interlock between the open end and 4. Al folded box made from al one-piece blank comprising a sheet of material having delinedtherein a top, closed end, bottom and open end ina line through-'the center of the sheet, top and bottom side walls laterally of the top. and bottom, respectively, Wings projecting beyond the ends of the top 'side walls, a tab proiecting beyond the open-end, projections from the Wings located at the corners thereof adjacent the top, and slit-s formed in the line between the tab and the open end with which the projections are adapted to interlock when the box isset up.
